WebFeb 1, 2024 · Binary Lifting is increasing the value of the given number by powers of 2 (done by flipping bits) ranging from 0 to N. We will be considering a concept similar to lifting binary trees where we will be finding the initial value of 'P' index. This is increased by flipping bits making sure the value is not greater than X. Binary Lifting is a dynamic programming approach where we pre-compute an array memo [1, n] [1, log (n)] where memo [i] [j] contains 2^j-th ancestor of node i. For computing the values of memo [] [], the following recursion may be used memo state: memo [i] [j] = i-th node’s 2^ (j)th ancestor in the path memo initialization:
